[Timur Kuran] now has a new book out — The Long Divergence: How Islamic Law Held Back the Middle East. The book explains a large part of why the Middle East and Turkey fell behind the West and law and economics has a lot to do with it. Various laws in Islamic societies were not conducive to large-scale economic structures, at precisely the time when such structures were becoming profitable and indeed essential as drivers of economic growth. This is not a book of handwaving but rather he nails the detail, whether it is on inheritance law, contracts, forming corporations, or any number of other topics.
